4.3.1 Cable Select (CS) Jumper
When a Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drive and another ATA hard disk drive are daisy-chained together, they can be configured as Master or Slave either by the CS or DS jumpers. To configure the drive as a Master or Slave with the CS feature, the CS jumper is installed (1). The drive's position on the 80 conductor Ultra ATA data cable then determines whether the drive is a Master (Device 0) or a Slave (Device 1). If the drive is connected to the end of the Ultra (cable Select) data cable the drive is a Master. If the drive is connected to the middle connection it is set as a Slave.
Once you install the CS jumper, the drive is configured as a Master or Slave by the state of the Cable Select signal: pin 28 of the ATA bus connector. Please note that pin 28 is a vendor-specific pin that Maxtor is using for a specific purpose. More than one function is allocated to CS, according to the ATA CAM specification (see reference to this specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is configured as a Master. If it is a 1 (high), the drive is configured as a Slave. In order to configure two drives in a Master/Slave relationship using the CS jumper, you need to use a cable that provides the proper signal level at pin 28 of the ATA bus connector. This allows two drives to operate in a Master/Slave relationship according to the drive cable placement.
The Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drives are shipped from the factory as a Master (Device 0 - CS jumper installed).

the CS position may be stored on the PK jumper pins.
4.3.2 Drive Select (DS) Jumper
You can also daisy-chain two drives on the ATA bus interface by using their Drive Select (DS) jumpers. To use the DS feature, the CS jumper must not be installed.
To configure a drive as the Master (Device 0), a jumper must be installed on the DS pins.
Note: The order in which drives are connected in a daisy chain has no significance.
4.3.3 Master Jumper configuration
In combination with the current DS or CS jumper settings, the Slave Present (SP) jumper can be implemented if necessary as follows:
Note: The CS position doubles as the Slave present on this drive.
• When the drive is configured as a Master (DS jumper installed or CS jumper installed, and the Cable Select signal is set to (0), adding an additional jumper (both jumpers DS and CS now installed) will indicate to the drive that a Slave drive is present. This Master with Slave Present jumper configuration should be installed on the Master drive only if the Slave drive does not use the Drive Active/Slave Present (DASP–) signal to indicate its presence.
4.3.4 Jumper Parking (PK) Position
The PK position is used as a holding place for the jumper for a slave drive in systems that do not support Cable Select. The pins used for the parking position are vendor unique.
Installation
4.3.5 Alternate Capacity (AC)
For user capacities below 66,055,248 sectors (32GB), inserting the AC jumper limits the Number of Cylinders field 1 to a value of 16,383, as reported in IDENTIFY DEVICE data word. This allows software drivers to determine that the actual capacity is larger than indicated by the maximum CHS, requiring LBA addressing to use the full capacity.
A summary of these effects for the Maxtor DiamondMax Plus8 drives is shown in the following table:

CAUTION: The PCB is very close to the mounting holes. Do not exceed the specified penetration for the mounting screws. The specified screw penetration allows full use of the mounting hole threads, while avoiding damaging or placing unwanted stress on the PCB. Figure 4-7 specifies the mini- mum clearance between the PCB and the screws in the mounting holes.
The Maxtor hard drive design allows greater shock tolerance than that afforded by larger, heavi- er drives. The drive may be mounted in any attitude using four size 6-32 screws with 3 mm maximum penetration and a maximum torque of 5-inch pounds. Allow adequate ventilation to the drive to ensure reliable operation.

4.4.1 Orientation
The mounting holes on the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drives allow the drive to be mounted in any orientation. Figure 4-6 show the location of the three mounting holes on each side of the drive. The drive can also be mounted using the four mounting hole locations on the PCB side of the drive.
Note: It is highly recommended that the drive is hard mounted on to the chassis of the system being used for general operation, as well as for test purposes. Failure to hard mount the drive can result in erroneous errors during testing. Drives can be mounted in any orientation. Nor- mal position is with the PCB facing down. All dimen- sions are in millimeters. For mounting, #6-32 UNC screws are recommended.

To connect the drive to the motherboard, use a 40 conductor ribbon cable (80 conductor ribbon cable if using Ultra ATA/66/100 or /133 drive) 18 inches in length or shorter. Ensure that pin 1 of the drive is connected to pin 1 of the motherboard connector.
4.7 FOR SYSTEMS WITH AN ATA ADAPTER BOARD
To install the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drive in an AT-compatible system without a 40-pin ATA bus connector on its motherboard, you need a third-party IDE-compatible adapter board.
4.7.1 Adapter Board Installation
Carefully read the manual that accompanies your adapter board before installing it. Make sure that all the jumpers are set properly and that there are no address or signal conflicts. You must also investigate to see if your AT-compatible system contains a combination floppy and hard disk controller board. If it does, you must disable the hard disk drive controller functions on that controller board before proceeding.
Once you have disabled the hard disk drive controller functions on the floppy/hard drive controller, install the adapter board. Again, make sure that you have set all jumper straps on the adapter board to avoid addressing and signal conflicts.
Note: For Sections 4.7 and 4.8, power should be turned off on the computer before installing the drive.
Installation
4.7.1.1 Connecting the Adapter Board and the Drive
Use a 40-pin ribbon cable to connect the drive to the board. See Figure 4-8. To connect the drive to the board:
1. Insert the 40-pin cable connector into the mating connector of the adapter board. Make sure that pin 1 of the connector matches with pin 1 on the cable.
2. Insert the other end of the cable into the header on the drive.
When inserting this end of the cable, make sure that pin 1 of the cable connects to pin 1 of the drive connector.
3. Secure the drive to the system chassis by using the mounting screws, as shown in Figure 4-9.

4.8 TECHNIQUES IN DRIVE CONFIGURATION 4.8.1 The 528-Megabytes Barrier
Older BIOS that only support Int 13 commands for accessing ATA drives through DOS based operating systems will be limited to use only 1024 cylinders. This will reduce the effective capacity of the drive to
528Mbytes.
Whenever possible the Maxtor DiamondMax Plus8 20/30/40GB AT drive should be used on systems that support LBA translation to ensure the use of the entire capacity of the disk drive. If that is not possible the following are some techniques that can be used to overcome this barrier.
Mounting Screws
Mounting Bracket ATA-Bus Interface Cable
Installation
• Use a third party software program that translates the hard drive parameters to an acceptable configuration for MS-DOS.
• Use a hard disk controller that translates the hard drive parameters to an appropriate setup for both MS-DOS and the computer system’s ROM-BIOS.
• Insert the Alternate Capacity (AC) jumper on the drive (see Section 4.3.5).
4.8.2 The 8.4-Gigabytes Barrier
Newer BIOS’s allow users to configure disk drives to go beyond the 528MB barrier by using several BIOS translation schemes. However, while using these translations the BIOS using Int 13 functions are limited to 24 bits of addressing which results in another barrier at the 8.4GB capacity.
To overcome this barrier a new set of Int 13 extensions are being implemented by most BIOS manufacturers. The new Int 13 extension allows for four words of addressing space (64 bits) resulting in 9.4 Terrabytes of accessible space.
Whenever possible the Maxtor DiamondMax Plus8 20/30/40GB AT drive should be used on systems with BIOS that support Int 13
extensions. If that is not possible the following are some techniques that can be used to overcome this barrier: Use a third party software that supplements the BIOS and adds Int 13 extension support.
• Obtain a BIOS upgrade from the system board manufacturer.
Many system board manufacturers allow their BIOS to be upgraded in the field using special download utilities.
Information on BIOS upgrades can be obtained on the System Board Customer Service respective web sites on the Internet.
• Insert the Alternate Capacity (AC) jumper on the drive (see Section 4.3.5).
4.8.3 Operating system limitations
Most popular operating systems available today have additional
limitations which affect the use of large capacity drives. However, these limitations can not be corrected on the BIOS and it is up to the operating system manufacturers to release improved versions to address these problems.
The most popular operating systems available today, DOS and Win 95, use a File Allocation Table (FAT) size of 16 bits which will only support partitions up to 2.1GB. A newer release of Win 95 called OSR2 with a 32 bit FAT has been released to system manufacturers only. This new FAT size table will support partitions of up to 2.2 Terrabytes.
4.9 SYSTEM STARTUP AND OPERATION
Once you have installed the Maxtor DiamondMax Plus8 20/30/40GB AT hard disk drive, and adapter board (if required) in the host system, you are ready to partition and format the drive for operation. To set up the drive correctly, follow these steps:
1. Power on the system.
2. Run the SETUP program. This is generally on a Diagnostics or Utilities disk, or within the system’s BIOS. Some system BIOS have an auto-detecting feature making SETUP unnecessary.
3. Enter the appropriate parameters.
The SETUP program allows you to enter the types of optional hardware installed—such as the hard disk drive type, the floppy disk drive capacity, and the display adapter type. The system’s BIOS uses this information to initialize the system when the power is switched on. For instructions on how to use the SETUP program, refer to the system manual for your PC.
During the AT system CMOS setup, you must enter the drive type for the Maxtor DiamondMax Plus8 hard disk drives. The drive supports the translation of its physical drive geometry parameters such as cylinders, heads, and sectors per track to a logical addressing mode. The drive can work with different BIOS drive-type tables of the various host systems.
You can choose any drive type that does not exceed the capacity of the drive. Table 4-3 gives the logical parameters that provide the maximum capacity on the Maxtor DiamondMax Plus8 family of hard disk drives.
Table 4-3 Logical Addressing Format
Note: *Capacity may be restricted to 8.4GB (or less) due to system BIOS limitations. Check with your system man- ufacturer to determine if your BIOS supports LBA Mode for hard drives greater than 8.4GB. Default logical cyl- inders is limited to 16,383 as per the ATA-4 specifica- tions.
To match the logical specifications of the drive to the drive type of a particular BIOS, consult the system’s drive-type table. This table

You must choose a drive type that meets the following requirements:
For the 20, 30 and 40 GB:
Logical Cylinders x Logical Heads x Logical Sectors/Track x 512 = 8,455,200,768
4. Boot the system using the operating system installation disk—
for example, MS-DOS—then follow the installation instructions in the operating system manual.
ATA BUS INTERFACE AND ATA COMMANDS
This chapter describes the interface between DiamondMax Plus8 hard disk drives and the ATA bus. The commands that are issued from the host to control the drive are listed, as well as the electrical and mechanical characteristics of the interface.
5.1 INTRODUCTION
Maxtor DiamondMax Plus8 hard disk drives use the standard ATA/ATAPI interface. Support of various options in the standard are explained in the following sections.
5.2 MECHANICAL INTERFACE 5.2.1 Signal Cable and Connector
The Maxtor DiamondMax Plus8 hard disk drive contains a 40-pin unitized connector for both signal and power connections as well as configuration jumpers.
The dimensions and specifications of the unitized connector comply with Annex.
A in the ATA/ATAPI standard.
The Maxtor DiamondMax Plus8 drives require the use of an 80 conductor cable (ATA/ATAPI-6, Annex. A, Figure A.4 and description) to support the drive’s Ultra DMA capability.
5.3 ELECTRICAL INTERFACE 5.3.1 ATA Bus Interface
5.3.1.1 Electrical Characteristics
Signals on the ATA interface are assigned to connector pins according to Annex. A in the ATA/ATAPI-6 standard for the 80 conductor cable assembly. The signaling protocol complies with clause 9 and signal timing complies with clause 10 of the standard.
The Maxtor DiamondMax Plus8 hard disk drives support all Ultra DMA Data Transfer modes (0 - 5) defined in the ATA/ATAPI-6 standard. In addition, these drives support Mode 6, and can send and receive data at the full 133MB/s transfer rate.
